Machine Learning Engineer (TTS)

We are fully Remote and can hire across Europe! At Praktika.ai we are on a mission to deliver efficient and engaging learning experiences for billions of students worldwide by bridging the gap between learning apps and human tutors. We have done this by creating a fully automated language tutorship experience powered by generative AI Avatars. After raising $30 million in Series A funding, we are growing and looking for a TTS/SST Machine Learning Engineer to join us! We are a global small team of 40 innovators who are pushing the boundaries of what's possible in language learning and tutoring. This is a unique opportunity to shape the voice of next-generation AI systems — from real-time conversational pipelines to emotionally expressive speech synthesis. If you're passionate about TTS, real-time AI, and scaling machine learning systems, we'd love to talk to you. In this fast-paced environment we like independent self-starters who can work well in a team as well as unassisted and who enjoy the working environment of an early-stage startup. What You'll Do with us: Design, integrate, and optimize Text-to-Speech (TTS) systems within real-time conversational AI pipelines. Fine-tune models based on user feedback, improving clarity, naturalness, and emotional expression in voice output. Contribute to customer-specific deployments with high adaptability and quick turnaround requirements. Collaborate with ML, product, and engineering teams to ensure seamless voice experiences across our platform. What we're Looking For from you: Strong proficiency in Python, with deep knowledge of software development principles, architecture patterns, and ML model integration. Hands-on experience with TTS systems (e.g., Tacotron, FastSpeech, VITS) and an understanding of SST pipelines. Familiarity with real-time AI systems, including LLM integration and latency-sensitive applications. Experience tuning and maintaining ML models for performance, scalability, and quality in production. Bonus: Experience with Pytest or other testing frameworks for ML systems.
